A new 20-year plan for management of dam operations calls for high flow releases to be performed on an annual basis if the right conditions exist.
Environmental groups are criticizing the final draft of a plan released by the Bureau of Reclamation Friday to manage the operations of Glen Canyon Dam for the next 20 years.
The plan calls for a more even monthly water release pattern from the dam and a continuation of the high-flow releases aimed at washing sand from tributaries into the mainstem of the Colorado River to build up sandbars.
